Ipomopsis half-hardy biennial

Ipomopsis half-hardy biennialThe Ipomopsis is a very beautiful half-hardy biennial, but difficult to cultivate. Some gardeners steep the seed in hot water before sowing it; but the best way seems to be to sow it in July in three inch pots in equal parts of sandy peat and loam, ensuring good drainage, and place it in a cold frame, giving it very little water.

When the leaves appear, thin out the plants to three or four in each pot. Replace them in the frame for a week or so, then remove them to a light, airy part of the greenhouse for the winter. During this period be careful not to over-water them.

In spring shift them into well-drained 4.5 inch pots, using the same kind of soil as before, and taking great care not to injure the roots; still give the least possible amount of water. If plenty of light and air be given, they will flower in July or August.

The height of the Ipomopsis is about two feet.
